THANKS TO BROAD adoption of sustainable construction practices, the asphalt pavement industry saved taxpayers more than $2.2 billion dollars during the 2011 paving season through the use of recycled materials and energy-saving warm-mix technologies.
According to a survey conducted by the National Asphalt Pavement Association (NAPA) in partnership with the Federal Highway Administration (FHWA), about 66.7 million tons of reclaimed asphalt pavement (RAP) and 1.2 million tons of reclaimed asphalt shingles (RAS) were collected in the United States during 2011 for use in new pavements. Also, about 19 percent of all asphalt produced in the country that year was made using warm-mix asphalt (WMA) technologies.
